Replacing coil balance

Question

The window weighs 20.6 lbs. The coil balance is a half inch wide. We can't find any no on it. I will include a picture. I hope this is all the info you need to tell us which one to use.

Hello, thank you for posting,

Your pivot shoe resembles the 15-111. Please review the dimensions to confirm a good fit! If the coil spring is a 1/2" thick, please review the Series 160 coil springs. For a 20.6 pound window, you can use (1) S160-10 coil on each side of the window.

Please review and let me know if you have any additional questions.
